lRensselaer and'State of New York',jh ave i n. vented, certain new and'useful Improvements in Falling-Mills for Fulling Glothyand we do hereby declare that the following lis a full de-` Figure 1 is a perspective view of the ma# ff chine. Fig. 2 is a vertical sectional view.

Fig. 3 is va view of the seriesof fullingrollers,

plates, and Fig. iV is a View of an elastic or yielding core-roller or cloth-holder 'with cloth or blankets arranged 'around it in readiness for the operation of fulling. f

The same letters refer to vlike partsineac'h In this invention our object'has been to prof duce a fullingmachine that shall full or mill the cloth eiectually in at least one-half of the time heretofore required for that operation,

and also to. obviate to a great extent the danger of straining or injuring the texture of the clothdnring the operation' of falling, as liable to heretofore by many of the old machines.

The improved resultsobtained withand by our machineare mainlypdneto an improved combinationI and arrangement of several mechanical devices, such as arranging in combination two fnlling-plates having given to them, respectively, reciprocating motions in opposite directions across and on thesnrfaeesof .the cloth interposed between them for the purpose of beingfulled, and in arranging in combinationwith said-plates feeding and drawlng rollers andr two seriesof falling-rollers, in the manner and for the purposes as hereinafter shown.

y Our improvement further consists in mounting theuppermost fullngplate and the' lower series of fulling-rollers in frames adjusted to move in 'gnides'in vertical directions, inthe manner and for the purposes hereinafter specied.` i

fIn order to enable persons skilled in ci nstructing fulling-mills to construct and vesc our improved machine,`we.proceed to 'describe its construction and operation.

' the frame-work ofthe machine.

The n ppermost fullingfplate, F, is attached to the frame B by means .ofthe oscillating kbearings G GG Gu- The pressure of theframe 'B and plate F 4npon the cloth being fnlled is regulated to a greater or less amount by ,means 1 ofthe weighted lever E.

K K is a frame containing a series of fnlling-rollers, d d. (Shown clearly in Figs. 2 and 3.)' This frame is permanently'bolted to the frameAA.` f

L L is a movable frame containing a series of fnlling-rollers, d de', and is arranged beneath the frameK. This frame L has a reciprocating rectilinear motion npon wheels running on the race or Ways'c' @communicated to it by means of the bell-crank M, one end of which is attached to and'partakes ofthe' reciprocating motion of the lower fnlling-plate, F. The

other arm of the crank is connectedio the frame K, as seenin Fig. 3. rlhis frameL and series of fulling-rollers have an adjustable rnotion in vertical direction, the raceway-frame e e being made to move upon guides, and Yis held in adjusted position by a weight adjusted upon the lever N. y

The feeding and drawing rollers w and vof the machine are operated as follows: A stud, g, is affixed to the moving frame L. The vforlred end of this stud, connects with a pin on the feeding-bar O, thus communicating to it a reciprocating motionin 4connection with that of the frame L. Eachend of this bar has a notch connecting it Wit-l1 the lever ends p p of the ratchet-wheels P and P', which. are fast to shafts of rollers, the levers having their bear- Y jury. Y

roller or corestock constructed by forming successive concentric Vlayers of canvas cloth,

.or inany other way by which substantially anV elastic roller may be made for the purpose intended. Fitted to the ends of thisyielding rollcrarethe canvas collars 'or caps t' t', hav-v ing eye-holes for passing the lacing-cords through.

v When the cloth istobe fulled in length and breadth, itis first treated in the usual way i t with the fulling-liquid, then rolled on acanvas core rolleror 'cloth-holder. The collars 'i t are broughtup to the ends of the cloth and laced across and around the roll, so aste coniine the cloth to the core or clothholder.- It is now placed between the falling-plates and power applied to the machine. The time 0f fulling will -vary according to quality of cloth; but after iifteen to twenty-iive minutes stop the machine, take out the cloth, and unroll it onto another roller, -soas to reverse the hides of the cloth'. Then place the cloth as rerolled again between thev pulling-plates andfull it as before done. This manner of proceeding will f cause the cloth to full equally, and the operas tions are kto berepeated as often as the opera# tor may deem necessary. Some pieces of cloth take 'an hour to full and some pieces take alonger time than that, accordingto quality of cloth.- This mode of fulling lcloth possesses the great advantage of preserving the 'cloth free from straining and otherin- The peculiar action ofv the fullingplates upon 'the cloth when the cloth is arranged upon an elastic clothefholder, as abovejdescribed, vcauses the cloth to 'roll'with a reciprocating motion between the fulling-plates,

- pressures. 1

-- This mode of fulling cloth is peculiarly-well adapted to fulling blankets, as by-forming theml *into a roll `upon the elastic core or cloth` holder the blankets are fulledequally in all parts land preserve a smoothness of surface and aj freedom from all: wrinkles not attained by other methods offulling.

` When the cloth is not to be fulled in the length, but in the width only, the end of the piece is passedY over the feeding-roller u, over the lower fulling-plate, F', over and under the drawing-roller o, then between the two series of fulling roll'ers, then under the feedingroller, and the ends laced together, forming an endless web, in the manner as shown by the blue lines in the drawings. In thisoperation of felling the cloth is passed by means of the v vfeeding and drawing rollers-continuously between the fulling plates and rollers until the operation of fulling is perfected, thecloth meantime being treatediwith the usual fullingliquids. The fulling-platesF and F are continued in motion while fulling the cloth in width only, iu vorder that the lower fullingplate, F', may give a reciprocating motion to the frame carrying the series of fulling-rollers d d, and also that the'feeding-roller u and drawing-roller o may be actuated in the manner and for the purposes herein set forth; but during said operation of fulling the cloth in width only the upper falling-plate,` F may be and is, by means of the adjustable frame in whichit is mounted,raised up from the lower fullingplate, sov that it shall not touch or have any action on the c1oth. It will hasten the falling process by bringing steam in contact with the cloth when `passing the series of full ing-rollers. The quantity of frietional contactofthe feed and drawing rollersaand o is regulated by a weight adjusted upon a lever, the friction-rollers w and y being mounted in frames having vertical adjustments, and connectedfwith` the adjusting apparatus in the manner substantially as seen in the annexed drawings. g

Having described our invention, we wish to' be understood'as laying no broad or eX- .elusive claim totfulling-plates or fulling-rollers, or feeding and drawing rollers, irrespective of their combinations and peculiar mode lof operation, substantially as herein described and shown. Nor do we lay -any,claim to weighted levers for regulating pressure upon `fulling plates or rollers or feed and drawing rollers; but 1 What wedo claim-as new, and desire to se cure by L tters Patent, is-- A1. The ulling-platesF and F', when conni bined one witlithe other, and having, respectively, reciprocating motionsl in opposite di- ,recti,on's',the uppermost plate having a variable pressure or frictional contact on the cloths surface, as herein described, .both plates being arranged and operating substantially in the manner and for the purposes, as herein set forth and shown.
